#include <rtl.h>

void ppp_close (void);

The ppp_close function disconnects the PPP link between the two modems.

The ppp_close function is in the RL-TCPnet library. The prototype is defined in rtl.h.

note

• You can call the ppp_close function when the PPP network daemon is either in client mode or in server mode.
• Since it is the PPP client that starts a dial-up connection, it is also the PPP client that usually disconnects the PPP link.
• The ppp_close function does not change the running mode of the PPP daemon. If the PPP daemon was in server mode, PPP daemon re-initializes the modem driver to accept further incoming calls.

The ppp_close function does not return any value.
